Agree. I have put some tunnel rams on that do well across the board, in town, etc. It has a lot to do with the combination. Don't overdo the top end.

Check out the designs that Weiand is using now. Smaller, thinner plenums, bet not 2" thick, so the carb barrels shoot straight down into each runner, but with a common plenum joined together almost like a big spacer plate under a single carb. The street power and response is good. I still like the vac sec, the new set he bought with mech sec and the tuning is rich, need time to do it.

A few years ago we built a 440 magnum mopar with long 30" cross ram intake from 1960 with dual Edel 600s out by the fenders. Everybody said it would be a dog above 5000 rpm. In a 4000 pound rig it went past 5500 like it went past 3000. You had to be careful to keep in under 6500 it wound so fast. Nobody could believe it, combination.... It would rev so fast spinning the 50 series tires/ spool that you could rev it to 6500, let off and the engine would be slowing down and the tach needle still going up.... idled at 700 like a kitten. (its sitting here on an engine stand now. First time at the strip did 8.40s with little traction 1/8.
Have another 426 wedge in the works now with 30" long rams.)

Said all that to say.... ram effect, too short or too long...... depends on scavenging
